For future people who are experiencing this issue. After a whole MONTH fo trying to fix this, I've found the solution in this loverslab thread. Basically, all you have to do is run this .bat script with admin privellages @echo off sc config winmgmt start= disabled net stop winmgmt /y %systemdrive% cd %windir%\system32\wbem for /f %%s in ('dir /b *.dll') do regsvr32 /s %%s wmiprvse /regserver winmgmt /regserver sc config winmgmt start= auto net start winmgmt for /f %%s in ('dir /s /b *.mof *.mfl') do mofcomp %%s Then, try FNIS. If it works, stop here. If it doesn't open an admin cmd and write winmgmt /verifyrepository Winmgmt /resetrepositoy net localgroup "Administrators" "NT Authority\Service" /add Then, try FNIS again. It still dosen't work, try doing the .bat script one more time. You're welcome.
